Resumo:  The aim of this study was to evaluate the Enhanced Vegetation Index (EVI) variation between crop-livestock integration (iLP) and extensive (EXT) systems, as well as between crop-forest-livestock integration systems (iLPF) with 14 and 22 m of trees spacing. For EVI values extraction from each production system, 33 images were used between April 2013 and October 2016, 24 in dry periods, between April and September, and 9 in rainy periods, between October and March. For iLP x EXT, in the rainy periods a difference between 8 of the 9 evaluated dates (88.9%) was observed. In 7 of these 8 dates, the iLP presented higher EVI values than the EXT (87.5%). In the dry periods, the difference occurred in 18 of the 24 dates (75%). In 10 of the 18 dates, the iLP presented mean values of EVI greater than the EXT (55.6%). For ILP14 x iLPF22, rainfall periods differed in 7 of the 9 dates (77.8%). Of the 7 dates, in 4 of them, the iLPF14 had EVI values higher than the iLPF22 (57.1%). In dry periods, the difference occurred in 22 of the 24 dates (91.6%). Of the 22 dates, in 19 of them, the iLPF14 had EVI values higher than the iLPF22 (86.4%). In the whole period, discrimination between the iLP x EXT and iLPF14 x iLPF22 systems was observed in 78.8% and 87.9% of the analyzed dates, respectively.
